Debate: Street Dogs' Role in Urban Safety and Ecosystems

Some people want to move stray dogs because they worry about people getting bitten.

But, others say dogs help keep cities safe by barking at strangers and scaring away thieves.

They also help control the number of rats and other pests.

Experts suggest that fixing the dogs by vaccinating and sterilizing them is the best approach, like some cities are doing.

Removing dogs can cause problems in the environment, so keeping them and taking care of them may be the best solution.
